Route selection (Routesel) process in GreedLea routing protocol for Internet of Vehicle (IoV) network environment

The low road efficiency problem triggered by the congestion and traffic accident is the reason of enhancing conventional transportation system in the world. It showed an awful picture of increasing traffic accidents with the growing number of vehicles. Road efficiency is constantly the main issue in the transportation system, hence supporting road efficiency must be in line among the traffic safety idea. Particularly, IoV is a main factor in Vehicle Cyber Physical Systems (VCPS). Road side unit (RSU) is an important factor for Vehicle to everything (V2X) communication, where it is an access point for linking the IoV network to the other networks [3]. In the IoV, the information exchange is generally produced of V2X which is vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V). It is important that safety message such as road condition, traffic information and traffic accidents consistently delivered to other vehicle in a timely manner for safety applications. Therefore, a number of studies have been done to design and develop a dependable routing protocols in Vehicular Ad-hoc Network (VANET). Though, in VANET, a transmission using single hop is generally incapable to serve all the proposed receivers because of partial radio range across a long distance. Consequently, the integrated routing protocol is needed to improve a communication system between vehicles in IoV network. Moreover, achieving a stable level performance in term of high throughput, less packet loss and less link failure in IoV is a challenging problem. In this paper, those key performance is analyzed and has been discussed in result section. From the results, it shows that the GreedLea routing protocol delivered 10% improved performance compared to existing Greedy perimeter stateless routing (GPSR) routing protocol in term of packet delivery ratio, average delay and path loss.
